Electrohydrodynamic effects on flow redistribution and convective boiling in horizontal concentric tubes under high inlet quality conditions.

Author(s) : NORRIS C. E., COTTON J. S., SHOUKRI M., et al.

Summary

An experimental investigation was conducted to study the mechanisms of the electrohydrodynamic flow boiling in a horizontal concentric flow channel. Experiments were conducted for inlet qualities of 20 to 50%, mass fluxes from 100 to 250 kg/m2s, and applied voltage from 0 to 10 kV. Time-dependent local surface temperatures along the flow channel, pressure drop, heat flux, inlet and outlet flow regime, and void fractions were measured. The results show that the electrohydrodynamic forces may significantly affect heat transfer through the reconstruction of the phase distribution along the length of the heated channel.
